Data Models and Data processing in GISPE & PLS

Steve Ramroop, Ph.D.

This course is the third course of a series of GIS courses. The understanding from this course goes together with the other courses in the series of GIS courses. This course presents a study of the data models, data structures, data management, and data processing adopted in a Geographic Information System (GIS). The course describes the importance of having data in the format that is suitable for the intended GIS application. In addition there is the need to model the phenomena being mapped. The course presents the various database models adopted over the years. The various levels of data modeling are explained and the importance of having a model is identified. The course describes the two types of data structures: vector and raster. Their characteristics, creation methods, and storage methods are identified. In the concluding lecture of this course are presented some of the typical analyzing capabilities of all GIS software.

This course includes a multiple-choice quiz at the end of each of the five lectures, which is designed to enhance the understanding of the course material.
